Years later, I had left the BRL, spent three years as
a Rutgers
administrator and was working for a small startup in Virginia. There was
a MIPS workstation there. I was slogging along using ed (my employees
always were amazed that if there was no emacs on the system, I just used
ed, having never learned vi). Not thinking about it, I attempted to
retrieve a backgrounded job by typing “fg.” To my surprise the shell
printed “Job control not enabled.” Hmm, I say. That sounds like my error
message. “set -J” I type. “Job control enabled.” Hey! This is my
shell. Turns out Doug Gwyn put my mods into his “System V on BSD”
distribution tape and it had made its way into the Mach code base and so
every Mach-derived system ended up with it. Certainly, I found it convenient.
To tie a couple of recent threads together: Ron's shell ended up as /bin/sh
on the NeXT machines.
